All of the following expressions are equal except 4^2/4^5 4-^3 1/4^3 4^5/4^2

D.

Step-by-step explanation:

We are asked to find the expression, which is not equivalent from our given choices.

A.

Using exponent property , we will get:

Using exponent property , we will get:

Therefore, option A, B and C are equivalent.

Let us check option D.

D.

Using exponent property , we will get:

Therefore, option D is the correct choice.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
